python | data types and transformations

In the code sequence below, I have no problem for "int to float", but I have a problem for "float to int".

Am I missing something? Can you help me to understand?

age         = 28
weight      = 55.6

# int to float

result = float(age)
print(result)

#float to int
result = int(weight)
print(weight)

I was expecting an integer result, but the decimal value keeps returning.
